HYDRAULIC PUNKA-IVIOTOR.

SPECIFICATION forming part of .Letters Patent No. 671,455, dated April 9, 1901 Application led March 8, 1900. Serial No. 7,912. (No model.)

To a/ZZ whom, t may concern:

Be it known that I, HEINRICH SPHL, a citizen of the Confederation of Switzerland, residing at St. Gall, in the Confederation of Swit- Zerland, haveinvented a new and useful Hydraulic Punka-Motor, of which the following is a specification.

Punkas generally are employed in hot countries for cooling the atmosphere in diningrooms, sleepingrooms, ship cabins, or the like; but they also can be used in cold countries for great halls, such as theaters, concert-halls, or the like.

The present invention relates to a hydraulic motor by means of which impulsion can be imparted to one or several punkas.

A chief feature of my invention is that the motor Works quickly and quietly. A small quantity of Water is necessary for driving my motor,and the Water can be pumped back into the receptacle from Which it is drawn olf, so that its driving is not expensive.

My motor does not need much space and no attending.

My invention will be better understood with reference to the accompanying drawings, in Which- Figure 1 illustrates a diagrammatic view of my hydraulic punka-motor moving two series of punkas. Fig. 2 illustrates a Vertical elevation of a punka. Fig. 3 shows a vertical section through the motor. Fig. 4 is an elevation View of the same, part being in section. Fig. 5 is a top view of the motor. Figs. 6 and 7 are sections through line :rnc of Fig. 3, the cock being in different positions. Fig. Fig. 9 is a section through y' yof Fig. 8. Fig. 10 is a section through zzof Fig. S. Fig; 11 partly illustrates a vertical section of a modified construction of the motor.

My hydraulic punkamotor consists of au open cylinder l, Within Which is movably ar-` ranged the piston 2, the rod of which is linked to the arm 3 of a crank-lever 3 4, fixed to the motor-casing. The arm 4 is provided with a toothed segment 5, engaging With the toothed pinion 7, arranged upon the shaft 6. Upon this shaft also is fixed a rope-disk 8, carrying the rope 9, which is xed to a spoke of the disk 8. The rope 9, in the example illustrated having two branches, is conducted over guide-rollers 10, and its branches are connected to the punkas 11. Below the cylinder 1 a distributing-cock 13 is arranged within a casing 12 in such a manner that its channel 14 either, Figs. 3 and 6, is in connection with the Water-admission pipe 16 and with a bottom opening 15 of the cylinder, Fig. 6, or in the second position, Fig. 7, is in connection With the exhaust-pipe l7 and with the bottom opening 15 of the cylinder. The cock is provided with a prolongation, to Which is iixed a double lever 18, the movement of which is determined by stops 19 and 20. A buffer-roller 21, of soft material-as, for instance, caoutchouc or the like-is xed to said lever to soften the noise. A spoke of the rope-disk 8 also is provided With a roller 22, of soft material. This roller has the purpose to act upon the double lever 18 and to effect automatically the cock reversal. The `latter also might be eected by means of connection-pieces 23 and 24. Within the exhaust-pipe 17 I have arranged a screw 25, by which the diameter of the pipe can be lessened at convenience, so that no cock reversal is possible and no impulsion is imparted to the punkas before they have not swungback completely. A semi- ,circular channel 27, Figs. S to 10, leads from the en trance-opening 26 of the cock-casing l2 to a recess 28, arranged within the cock-casing diametricallyas to said opening 26 for the purpose of balancing the cock, owing to the counter-pressure of the Water, and to obtain thereby an easy play of the cock. In order to secure an exact cock reversal, the segment 5 is provided with a pin 29 and the toothed pinion 7 with a flange 30, having a depression 31. When the segment engages exactly with the pinion 7, the pin 29 during the oscillation of the segment 5 enters the depression 31, while when the exact engagement does not take place the pin 29 meets the flange, brakes the segment, and thereby shows the inexact engagement' or the Wrong cock reversal to the attendant.

The modus operandi of the motor is as follows: A slight upward traction is im parted to the rope 9 by hand. Hereby the rope-disk S, Fig. 4, is turned in the sense of the hand of a clock, and the cock 13 is turned in the position illustrated in Figs. 4 and 6 as soon as the roller 22 abuts against the lever 18. The

IOO

water enters the cylinder and pushes the piston upward. This ascending motion of the piston, owing to the transmission of the cranklever 3 4, the segment 5, the toothed pinion 7, and the shaft 6, the rope-disk 8 is turned in the direction indicated by the arrow 32, Fig. 4 Hereby an impulsion is given to the punkas connected with lthe rope 9, Fig. 1. After completion of the rotation the roller 22 meets again the cock-lever 18, reverses the cock into the position according to Fig. 7, in which cylinder 1 is connected with the exhaust-pipe 17. The weight of the piston 2, increased by a spring 33, arranged upon the axle of the crank-lever 3 4 and the suction effect caused by the exhaust-water, effects the turning back of the rope-disk 8 in the direction of the arrow 34, Fig. 4. The punkas now can freely swing back. When the rope-disk 8 completely is turned backward, the roller 22 meets again the lever 18 and reverses the cock 13 into the position illustrated in Fig.'

. 5 in this construction totally being omitted.

This modification is more simple, but more space is necessary for the same. Evidently my motor can be driven by compressed air instead of water.

Having thus Yfully described the nature of this invention, what I desire to secure by Letters Patent of the United States is- 1. In a hydraulic punka-motor, the combination with an open cylinder and a piston, of a crank-lever fixed to .the motor-casing, one arm 3 of said lever being linked to the pistonrod, a toothed segment 5 provided on the other arm 4 of said crank-lever, a toothed pinion 7 arranged upon a shaft 6 and engaging with said segment, a rope-disk 8 arranged upon the shaft 6 and carrying the rope which is fixed to a spoke of said disk, a cock 13 arranged in a casing below the cylinder and adapted to alternatively establish communication of the cylinder with the water-admission pipe and with the exhaust-pipe, a double lever 18 fixed to the prolongation of said cock, stops determining the movement of said lever, a buffer-roller 21 of soft material Xed to said lever, a roller 22 of soft material provided on a spoke of the rope-disk, said roller acting upon the double lever 18, the whole for the purpose as set forth.
